OF CLEVELAND, OHIO, A CORPORATION Specication of Letters Patent.

A Patented Feb. 5, 1907'.

Application led September 25, 1905. Serial No. 280,024.

. To aZZ'w/lwm it may concern.'

Beit known that I, PHILIP P. NUXGEssEE, a cltizen ofthe United States,residing at `Cleveland, in the county of Cuyahoga and State of Ohio,have invented certain new and useful Improvement-s in a CombinedBlowpipe and Soldering Attachment, and do declare that the following isa full, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to a combined blowpipe and soldering attachmentdesigned more especially for soldering bindingosts on drybattery cells,,but not necessari y limited to l this use.

' In the accompanying drawings, Figure 1 is a side elevation of thecomplete invention, comprisingl the blowpipe with gas connections andthe soldering attachment; and Fig. 2 is a cross-section on line zz,Fig. 1. Fig. 3 is a perspective view, reduced in size, of the combineddevice seen in Fig. 1 and of a can or cell with a binding-post thereonand showin how the can withthe post is held to the so dering-iron toeflect the soldering. Fig. 4 is a cross-section on line Fig. 1.

I do not claim herein that it is broadly new to use a blow ip e with gasas a means for heating or me ting solder for securing binding-posts tobattery-cells, because it was the practice prior to my invention to useblowpipes for this purpose, and the usual method of proceeding was toexpose the can with the binding-post thereon and the requisite solder tothe flame until the solder melted and fused into binding relation withthe parts, when the work was supposed to be finished; but this mannerlof proceeding was found to be defective and. unsatisfactory in results,first, because is did not provide for mechanical ap- "plication` of thesolder, and, secondly, because at the best the operation was slowrelatively. Now I have overcome both these material objections byattaching a solderingiron directly tothe blowpipe and sustaining thesame in such relation to Athe flame that I can utilize the iron and notdepend on the flame to do the soldering. A reference to the constructionand relation of the parts will make this clear. Thus the blowpipe, asshown herein, is Vadapted to burn gas or vapor, and the said pipeproper, A, has air connection B and gas or vapor pipe connection C, andany usual or needed means may-be em loyed to regulate the flow of volumeof bot air and gas.

I D represents the soldering-iron, which is removably or detachablysecured in working position by relatively wide clamps or jaws Eproviding broad bearing-surfaces and adapted to be clamped upon bot-hpipe A and iron D in a rigid manner, so that the relations of theseparts' will not change during use. Screwbolts 2 engage through saidclamps between tube A and iron D, and any suitable support for thedevice as a whole may be provided. e

The working end of iron D is. curved downward over the end of pipe A,and at a suitable distance from the end of said pipe, where the flanepresumably is r-.ost intense, the said iron is bent inward at 3 atsubstantially right angles directly in the path of the flane, while theeXtrenzity 4 of the said. iron beneath said bend isbent back at an acuteangle and provided with a flattened surface 5 on its bottom. This latterportion of the iron is designed to dothe work, and its exposure to theHair-.eis such that it is' brought to at least a red heatsandniaintained at this heat during the entire tine the soldering operationsare continued. This works two very iniportant advantages, as alreadysuggested,

because it provided a fixed iron by 'means of which the solder is meltedand applied .about the edge of the binding-post very nir-.ch as would bedone by a hand-tool, the cellbeing nzanipulated as this operationproceeds instead of the tool, and the further advantage of having afixed tool always heated and ready to do soldering the ntonient it istouched, instead of waiting until the parts `becone heated to afizsingtenperature, as

formerly when no such iron was known and the blowpipevalone was used.'The iron D preferably consists oi what' is known as Norway iron, becausethis particular kind of iron has superior powers of endurance in thissevere use, and the said iron is niade of such length that asv it getsburnt away it ni ay be reshaped at the using end and let out at clanpsE. Hence said iron is in the form of a rod or bar of suitable size inlength and cross-section.

In Fig. 3 the can or cell G, which has the IOS binding-post 6 set in theedge thereof, is shown about as it is held by hand in relation to iron Dwhen soldering is being done. It will be noticed that the flattenedsurface 50i point 4 is `adapted to rest down upon the solder and a verylittle turning or movement of t-he cell is required to make the vsolderlovrwhere desi'ed. At the longest it is the Work of practicallyamoment', and the mechanical touch through ,point 4 makes the workpromptly effective.

What I claim is 1. A blowpipe having a downwardlycurved outer end, incombination with a soldering-iron D adjustably clamped upon said pipeand bent to'conform therewith and having its outer free end formed witha substantiallyvrightnn led portion?) and inclined extremity 4, am? saidend formed to substantially V shape and directly in line with thedischarge from the mouth of the said pipe.

2. A gas-heating blowpipe A bent downwardly at its outer end, 1ncombination with a soldering-iron secured thereto and having a solderingend substantially V shape in side elevation and the inner portions 3 ofsaid end. standing directly across the niouth of said pipe and the outerportion extending' at an inclination away from said portion 3 and in thesane vertical plane therewith and with the bent end of said pipe A, andin line with the discharge oi said pipe.

ln testimony whereof l sign this speciiicationin the presence of twowitnesses.
